feat: 实现模板片段权重配置功能

新功能:
- 模板片段级别的AI分类权重配置
- 权重继承机制（全局权重作为默认值）
- 批量权重配置操作
- 直观的权重管理界面

 后端实现:
- 新增 template_segment_weights 数据表
- 实现 TemplateSegmentWeightRepository 仓储层
- 实现 TemplateSegmentWeightService 业务逻辑层
- 新增 Tauri 命令接口

 前端实现:
- TemplateSegmentWeightEditor 权重配置编辑器
- SegmentWeightIndicator 权重状态指示器
- BatchWeightConfigModal 批量配置模态框
- 集成到模板详情页面

 测试:
- 单元测试覆盖核心功能
- 集成测试验证端到端流程
- E2E测试确保用户体验

 技术特性:
- 权重范围：0-100，数值越大优先级越高
- 支持单个和批量更新操作
- 事务处理确保数据一致性
- 类型安全的API设计

 文档:
- 完整的功能文档和使用指南
- 技术架构说明
- 最佳实践建议

这个功能将显著提升模板匹配的灵活性和准确性！

+# 模板片段权重配置功能
+
+## 概述
+
+模板片段权重配置功能允许用户为每个模板片段设置不同的AI分类权重，实现更精细的素材匹配控制。该功能将权重配置从全局级别扩展到模板片段级别，提供更灵活的匹配策略。
+
+## 功能特性
+
+### 核心功能
+
+1. **片段级权重配置**
+   - 每个模板片段可以有独立的权重配置
+   - 支持为不同AI分类设置不同权重值
+   - 权重范围：0-100，数值越大优先级越高
+
+2. **权重继承机制**
+   - 新片段默认使用全局权重配置
+   - 可以选择性地覆盖特定分类的权重
+   - 支持重置为全局默认权重
+
+3. **批量操作**
+   - 批量复制权重配置到多个片段
+   - 批量重置权重配置
+   - 批量应用自定义权重配置
+
+4. **可视化管理**
+   - 直观的权重指示器
+   - 实时权重预览
+   - 权重配置编辑器

+}

+  weights: SegmentWeightConfig[];
+}
+
+interface SegmentWeightConfig {
+  ai_classification_id: string;
+  weight: number;
+}
+```
+
+## 使用指南
+
+### 基本使用
+
+1. **查看权重配置**
+   - 在模板详情页面的轨道标签页中
+   - 每个片段显示权重指示器
+   - 悬停查看详细权重信息
+
+2. **编辑权重配置**
+   - 点击片段的权重配置编辑按钮
+   - 使用滑块或数值输入调整权重
+   - 点击保存应用更改
+
+3. **批量操作**
+   - 在轨道标签页点击"批量权重配置"
+   - 选择操作类型：复制、重置、自定义
+   - 执行批量操作
+
+### 高级功能
+
+1. **权重继承**
+   ```typescript
+   // 获取片段权重（包含默认值）
+   const weights = await TemplateSegmentWeightService
+     .getSegmentWeightsWithDefaults(templateId, segmentId);
+   ```
+
+2. **自定义权重**
+   ```typescript
+   // 设置自定义权重
+   await TemplateSegmentWeightService.setSegmentWeights(
+     templateId,
+     segmentId,
+     {
+       'classification_1': 95,
+       'classification_2': 30,
+       'classification_3': 85,
+     }
+   );
+   ```
+
+3. **重置权重**
+   ```typescript
+   // 重置为全局权重
+   await TemplateSegmentWeightService
+     .resetSegmentWeightsToGlobal(templateId, segmentId);
+   ```
+
+## 最佳实践
+
+### 权重配置策略
+
+1. **分层配置**
+   - 全局权重作为基础配置
+   - 模板级权重用于特殊需求
+   - 片段级权重用于精细控制
+
+2. **权重值设置**
+   - 0-20：低权重，较少使用
+   - 21-50：中等权重，常规使用
+   - 51-80：高权重，优先使用
+   - 81-100：最高权重，强制优先
+
+3. **批量操作**
+   - 使用模板复制快速配置相似片段
+   - 定期重置不需要的自定义配置
+   - 使用统计信息监控配置状态
+
+### 性能优化
+
+1. **缓存策略**
+   - 权重配置会被缓存以提高查询性能
+   - 修改后自动刷新相关缓存
+
+2. **批量操作**
+   - 使用批量API减少网络请求
+   - 事务处理确保数据一致性
+
+3. **索引优化**
+   - 数据库索引优化查询性能
+   - 复合索引支持复杂查询
+
+## 故障排除
+
+### 常见问题
+
+1. **权重配置不生效**
+   - 检查权重值是否在有效范围内（0-100）
+   - 确认AI分类是否激活
+   - 验证模板和片段ID是否正确
+
+2. **批量操作失败**
+   - 检查目标片段是否存在
+   - 验证权重配置是否有效
+   - 查看错误日志获取详细信息
+
+3. **性能问题**
+   - 检查数据库索引是否正常
+   - 监控权重配置数量
+   - 考虑清理无用的配置
+
+### 调试工具
+
+1. **日志记录**
+   ```rust
+   // Rust 后端日志
+   tracing::info!("权重配置更新: template={}, segment={}", template_id, segment_id);
+   ```
+
+2. **前端调试**
+   ```typescript
+   // 开发者工具中查看权重配置
+   console.log('Current weights:', weights);
+   ```
+
+3. **数据库查询**
+   ```sql
+   -- 查看片段权重配置
+   SELECT * FROM template_segment_weights 
+   WHERE template_id = 'template_id' AND track_segment_id = 'segment_id';
+   ```
